Odd Numbers

Luck in odd numbers. A major chord consists of a fundamental or
tonic, its major third, and its just fifth. According to the
Pythagorean-system, “all nature is a harmony,” man is a full chord;
and all beyond is Deity, so that nine represents deity. As the
odd numbers are the fundamental notes of nature, the last being deity,
it will be easy to see how they came to be considered the great or
lucky numbers. In China, odd numbers belong to heaven, and v.v. (See Diapason, Number.)

“Good luck lies in odd numbers ... They say, there is divinity in odd
numbers, either in nativity, chance, or death.” —Shakespeare: Merry
Wives of Windsor. v. 1.

No doubt the odd numbers 1, 3, 5, 7, 9, play a far more important
part than the even numbers. One is Deity, three the
Trinity, five the chief division (see Five), seven is the sacred number, and nine is three times three, the great
climacteric.
